ABSTRACT:
A system, method, and computer program product are provided for removing a register of a processor from an active state. In operation, an aspect of a portion of a processor capable of simultaneously processing a plurality of threads is identified. Additionally, a register of the processor is conditionally removed from an active state, based on the aspect.
